As continental plate converges with an oceanic plate, the (1)______(continental, oceanic)
plate dives under the (2)_____(continental, oceanic) plate. The process of diving down towards
the mantle is called (3)______(subduction, floatation). When the leading edge of the
subducting plate reaches the mantle, it melts turning into (4)_______(magma, crust) which builds up
a pressure making it push the ground above it forming at the surface a (5)_______(volcano,mountain). At the oceanic plate, a depression called (6) _______(trench, fault) is formed along the
boundary. Parallel to it, a series of volcanoes called (7)_______(volcanic island, volcanic island
arc) may be formed. Simultaneous with the convergence, the ground may shake and so, we experience
an earthquake. This shaking may disturb the water surface and may make the water flip upwards to a
certain height. This event is called (8)______(tsunami, wave).
B) When two oceanic plates
converge, the denser plate subducts. Once its leading edge reaches the mantle, it melts into a magma,
builds up a pressure that makes it push the ground above it, forming a (9)______(volcanic island
mountain). At the collision zone, a crack called (10)____(trench, fault) is formed. This
depression could be the cause of the shaking of the ground which is felt as
(11)_____(earthquake, storm). At the water surface, the overriding plate may push a big
amount of water causing it to flip upwards forming a (12)____
(tsunami, wave). C) The
convergence between two continental plates results to a landform called(13)____
(volcanic
arc, mountain ranges). Since both plates have the same densities, no plate subducts under the other
There is (14)____
(no volcanic, volcanic) formation. However, since the ground
moves, a phenomenon called (15)______(earthquake, storm) may be felt in nearby places.
